Q: list two pros and two cons of Uniform Crime Report (UCR) data and two pros and two cons of self-report data.

A: Uniform crime report: pros 1. it is a very workable, by-the-numbers sort of system. 2. It's also been tried and tested for over 90 years, which means that it has withstood the test of time as a system that provides a good estimate of crime count. [ CONS 1. s that it only included crimes that were reported or detected. If for instance 3,000 rapes happened but none of them were reported, then

those statistics won't be found in the Uniform Crime Report. 2. did not give you an accurate look at crime in the United States, but rather a look at the crime that was reported or detected.
SELF REPORTING DATA: CONS 1. may be exaggerated; respondents may be too embarrassed to reveal private details; various biases may affect the results, like social desirability bias. 2. inherently biased by the person's feelings at the time they filled out the questionnaire. If a person feels bad at the time they fill out the questionnaire, for example, their answers will be more negative. If the person feels good at the time, then the answers will be more positive. PROS1. give us more detailed report, able to examine a large number of variables and can ask people to reveal behaviour and feelings which have been experienced in real situations. 2. allowing participants to describe their own experiences rather than inferring this from observing participants ]
